Physical Cartridge Installation
1. Insert the game cartridge:

- Gently push the cartridge (label side facing the back of the console) until it clicks.
2. Start the game:
- The game icon appears on the HOME menu. Select it to begin.
3. Mandatory update download (if internet is connected):

- If you do not connect to the internet, you can play the base version offline, but online features and many modes will be unavailable.
4. Final installation:

First Launch Setup
1. Launch the game by selecting its icon on the HOME menu.
2. Initial patch: If an update is needed, the game will download and apply it before the title screen appears.
3. Create/select an in-game save file:
- You’ll be asked to choose a user profile linked to your Nintendo Account.
- The game will create a save data slot for that user.
4. Internet connection check:

5. Nintendo Switch Online prompt:
- To enter online multiplayer lobbies (Turf War, Anarchy Battles, etc.), you must have an active Nintendo Switch Online subscription. The game will guide you to sign up or start a free trial if eligible.
6. Set game preferences:
- Adjust controls (motion or stick), audio settings, and language. These can be changed later from the Options menu.

Post-Installation Verification
After installation, verify the game is ready:
1. Check game version:
- From HOME menu, highlight Splatoon 3, press + → Manage Software → Version Info. The latest version should be displayed (e.g., 5.0.0+). If not, manually check for updates: select Update Via Internet.
2. Confirm save data:
- Launch the game and ensure your profile’s save file loads. You should see the title screen with your Inkling/Octoling.
3. Test online connectivity:
- Go to the menu and select Lobby → Start. If you have Nintendo Switch Online, you can queue for a Turf War. A successful connection indicates network setup is correct.
4. Run a data repair scan (optional):
- From HOME menu, highlight Splatoon 3, press + → Manage Software → Check for Corrupt Data. If no errors, the installation is healthy.
5. Storage usage check:
- System Settings → Data Management → Manage Software → select Splatoon 3. It should show around 6.0–7.0 GB used, depending on updates.

Additional Tips
- Redownload without re-purchasing: If you’ve bought Splatoon 3 digitally, you can redownload it anytime from the eShop under your account’s “Redownloadable Software” section.
- Use a microSD card: The internal storage of most Switch models is limited (32GB for standard, 64GB for OLED). A microSD card (UHS-I, speed class U1 minimum) is highly recommended for digital games.
- Archiving vs. Deleting: Archiving removes the game data but keeps the icon and save data. Deleting removes everything. To free space quickly, archive games you don’t play often.
- Region restrictions: Splatoon 3 is not region-locked on Switch, but some DLC or in-game events may be region-specific. Use an account matching your eShop region for consistent access.
